Not only that, we KNOW there is no secret. The government has openly admitted all along that the order had been given to shoot the plane down. The fighter jets just didn't get there until a few minutes after the plane went down itself.
Of course, there are a few who manage to spin a conspiracy theory out of this anyway, alleging that there's some wacko reason why the government will admit to giving the order yet not admit to "actually having it carried out." They just never get around to giving an explanation for such an argument that makes even the slightest sense. (Usually it's the standard hoary line that only worked up until 9/10: "The public wouldn't be able to handle the truth.")
In the end, interestingly enough, it's rather like the hair-splitting article that launched this thread. All that matters is that the government intended to take that plane down and has let the public know it. Once that's been established, what's the difference whether it went down due to an Air Force missile, a revolt by the passengers, or the actions of the hijackers themselves?
The theory has been advanced that Flight 93 was NOT to have been successfully crashed into the White House, the reason Bush was not present inside, just in case something went wrong, but was supposed to have been intercepted as *proof* of how our governmental protectors can get the job done some of the time. Unfortunately, the passengers aboard Flight 93 spoiled that plan and either caused the aircraft to be crashed before it could be taken out by a USAF aircraft, or worse, had actually regained control of the airplane and were downed on federal governmental orders anyway.
It would hardly surprise many americans to think that our own government would frame or kill its own citizens if we interfee with some of their not-all-that-well-crafted plans and schemes. And after the fact coverups of FedGov incompetence, blundering or criminality can be even more spotty.
